HAIR COMB.

;- Specification of Letters l atentfi- I "Application filed September 13, 1920. Serial No 409,878.

To all whom 2'25 may concern lie it known that I, JOHN Saonnn, a citi-Blackstock Road, Finsbury Park, London, England, have invented anImproved Hair Comb, of which the following is a specification.

My invention relates to a novel construction of comb particularlysuit-able for rei'i'ioving nits from the hair of persons heads, and fromthe hair of animals, such as dogs.

Combs for this purpose are usually made of flexible material such ascelluloid, bone and the like and possess the disadvantage that when inuse the teeth yield and allow the nits to pass between them.

The object of my invention is to overcome this disadvantage and to thisend I construct a comb of a practically rigid or non-tier;- iblematerial such as metal with very line divisions between the teeth and asit is difiicult to manufacture such a comb on account of the closespacing of the teeth I form the latter separate and secure them togetheror to a back or handle.

In a suitable arrangement for carrying out the invention each tooth isprovided with holes for the reception of pins or bolts for securing theteeth together or in a back or pieces or washers alternately betweenthem,

these distance pieces then providing the necessary spacing between theteeth In a further modification I make use of strips formed with teethat either end, the so-called backs being then provided in the middle andbeing connected together in any of the Ways above desrribed. By thesemeans two combs of different meshmay be] provided in one and the sameappliance.

In a modified construction according. to the invention the strips ofmetal or other material forming the teeth are reduced in thickness atthe tech end as compared with what may be termed the back portion, sothat, when the said strips are assembled to form the comb, the necessaryspace is left between the teeth. The strips may be se-' cured togetherby being clamped betweenv ta ed Aug e-192,2

two'end plates or strips ofpins portions andthe said plates; or the backportions may be soldered or welded together.

or bolts passed through holes in the back I I To enable the invention tobe fully understood, I will describe it by reference to the accompanyingdrawing in which Figure 1 irsa sectional elevation of one 1 form of combmade according tothe'invention. 7

" Figure 2 is a section on the line 2+2 Figure 1.

Figure 3 is an elevation of a portion of a comb illustrating amodification.

Figure 4 is an elevation illustrating a further modification, and 1Figure 5 is a section on the line 55'Figure 4:.

Referring firstto the construction of comb illustrated in Figures 1 and2, a indicates the strips constituting the teeth and b the two endplates or strips. 0 indicates a pair of pins or bolts which are passedthrough holes formed in each of the strips 41!. and the plates Z). Thestrips a and the .end plates 6 are threaded upon the said pins or bolts0 and.

cent strips on the respective bolts 0 the whole being then tightlyclamped together by means of the nuts 6, engaging the screwthreadedprojecting ends of the pins 0. In, 1

practice, the washers 0? may be made slightly thicker than the washersal so that, when the comb is assembled, the strips may be closertogether at the tooth than at the back end, 6 are screws engagingthreads in the pins 0 to. prevent the nuts 6 from becoming accidentallydetached from the said pins.

Figure 8 shows the modification of the comb in which the individualstrips a are re duced in thickness at the tooth end as compared with theback portion, the latter being I advantageously thicker than the saidtooth end at the parts embracing the bolts 0. This arrangement enablesthe washers d to bedispensed with.

In Figures 4 and 5 I have indicated a modification of the arrangementillustrated in Figure 3, in which modification. the strips a are formedwith back portions f which are soldered togetherand additionallysecured. in place by means of the. transverse pins or rivets g.

In the drawings single combs only are shown, but double combs may bemade by forming the strips (1 with teeth at both ends and extending theend plates 6 to correspond therewith. This arrangement is illustrated bydotted lines at h Figures 1 and 2.

As Will be understood, combs made according to the invention possesscertain advantages, since the Whole of the comb is composed ofan easilycleansable and un breakable material such as metal, and in those, formsin which the teeth are not solderedtogether the parts can be easilyseparated so as to render the cleansing operation thorough and.eflicient.

Claims:

1. A hair comb constructed of n'on-fiexible material, comprising teeth,provided portion comprising the teeth, to secure a firm grip by the handof the user.

2. A hair comb constructed of non-flexible material, comprising teeth,the upper ends of which are thickened to space them apart When securedtogether, each of said teeth being provided With a plurality ofappertures, one of said apertures being at the lower extremity of thethickened portion, and the other at the upper extremity of saidthickened portion pins adapted to be passed through said apertures forsecuring said teeth together. 7 4 3. A hair comb as claimed in claim 2,in Which the thickened portions at the upper ends of the teeth, form ahandle which is substantially rectangular in shape, to permit a firmgrip by the user.
